IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 171.955, dated January 11, 1876; application filed November 15, I875.

of the burner with the gallery removed; Fig.

3, a top view of the burner, the gallery being removed; and Fig. 4, a plan of the collar.

Like letters indicate like parts. The principal aim of the present invention is to provide means whereby a more brilliant illumination is obtained. It also relates to the provision for diminishing the liability of explosion, and for preventing flickering.

Referring to the accompanying drawing, A, Fig. 1, represents a burner, which, in its general construction, may be of any approved shape. B represents a tube, closely connected at its upper end with the under side of the burner, and depending therefrom. This tube, in shape, is similar to the ordinary wick-tube in the upper part of the burner, and it, in effect, is an extension of the wick-tube downward into the oil-chamber of the lamp, and, preferably, nearly to the bottom thereof. The tube is open at its lower end, and,also,toward thelower end, at either side b b, there are other openings. C, Fig. 1, represents an opening into the side of the base of the burner, just above the part H, which screws into the collar, and below the gallery G. It leads into the chamber in the base of the burner, in which the wick-raising mechanism is usually located. 0, Fig. 2, represents another opening in the bottom of the burner, leading upward from the oil-chamber (when the burner is in position) into the chamber in the base of the burner above described.- Saving these openings 0 0, this chamber, to prevent any escape of the gas from the oil-chamber of the lamp to the point of illumination above, is made tight,

and,'further, to .cut off all communication between the flame and the oil-chamber, I dispense with the gas-tube, which usually is arranged beside the wick-tube, and extends from the upper part of the burner downward through the bottom thereof, my aim being to discharge the gas (which, in my lamp, is generated even more freely thanin ordinary lamps)- entirely through the openings C G, and to the open air. D D D D, &c., represent openings in that part, I, of the burner which is immediately above the base of the'burner. They are arranged in the bottom of the part I, and are to admit the air in an upward direction into the space beneath the cone. E represents an open-work construction or gauze, which is arranged inthe, part I, and over the openings D D, 850., and is made to be detachable. F, Fig. 4, represents the collar. It is provided with a series of perforations, ffff, which oxtend from the top of the collar, and in such a manner as to provide for communication from the oil-chamber of the lamp directly outward to the open air.

In operation the wick is passed into the usual tube in .the burner, and also down through the tube B, which serves as a casing therefor. Two important results accrue from this arrangement. The surfaces of the tube being in contact with the wick, the liftingforce due to capillary attraction is increased. Further, the tube B, being composed of a suitable substance, serves to conduct the heat of the burner downward to the oil below, which, from being warmed, flows more readily up the wick and tube, and, also, is in abetter condition for burning and illuminating when it arrives at the top of the wick. In consequence, the brilliancy of the light (with a given size of wick) is greatly increased. Any gas that may be formed in the lamp escapes through the openings 0 G to the open air. These openings also afford an avenue for the colder air without to pass into the lamp, and, in passing, to cool the base of the burner.

exit being in the side of the burner,) and owing to the absence of the usual vent-hole, which is arranged vertically directly beside the wicktube, no downward current can carry the flame downward into the oil-chamber. The perforations f f f f in the collar F serve a similar purpose in the discharge of the gas from the oilchamber.

In consequence of the arrangement of the Further, owin g to the arrangement of these openings, (the r openings 1) D, &c., in the bottomof the part I, no side current of air can cause the flame to flicker. Dirt and soot are apt to collect inside the burner. These are caught upon the gauze E, which, being detachable, can be easily removed and the dirt emptied therefrom.

I am aware that safety and other tubes have been extended from the lampcollar downward to, or nearly to, the bottom of the oil-chamber;

but such tubes were mainly to cut off the escape of gas, through the burner, to the flame, and not to warm the oil or to facilitate its flow up the Wick by coming in contact with the wick and heating the oil during its ascent, as I have above set forth as the aim of my ini vention, and I disclaim them; but,

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

- 1. The combination of the burner A, tube 13,

. and openings 0 C, said tube being constructed and arranged-as described, and said openings being arranged as shown, substantially as and for the purposes shown.

2. The combination of the burner A, tube B, and collar F, said tube being constructed as described, andsaid collar being perforated, as shown, substantially as set forth,

JEAN SEGONDY.
